Abstract

We experimentally investigated the pressure-induced infiltration of a nanoporous silica-based energy absorption system modified by polyacrylic acid partial sodium salt (sodium polyacrylate). Under ambient conditions, sodium polyacrylate forms a soft matter with water. As the hydrostatic pressure increases, the dehydration of the soft matter occurs and the nanopores are filled by water molecules, accompanied by a significant energy dissipation. This result has fundamental scientific interest for understanding behaviors of confined liquids and great technological importance for developing advanced solid-like protective/damping materials.
